It forces the go block to wait until (walker (:left t)) pushes something --
that is, for the recursively-entered go block to complete. Similarly the
right branch is waited for before the parent go block completes. So forcing
an in-order traversal of the tree.

I believe Korma uses c3p0 for connection pooling right out of the box.

Hi John,
It's super easy to deploy Clojure web app (ring) to Amazon Beanstalk. I
think there were few blog posts about that.
Basically you just need https://github.com/weavejester/lein-beanstalk

This sounds like a classic knapsack problem. For such a small problem
space, a simple dynamic programming solution would suffice.
If you are interested in exploring this problem at a larger scale, I high

Thanks for putting this plugin together, very useful!
A couple of remarks:

I am stupid and recursion is clearly beyond my intellect. Martin Trojer has
a great blog post here which I learned a lot from but I don't understand

Well for creation itself, http://www.luminusweb.net/ represents best
practices with Ring, Compojure, and the usual attendant libraries.
For deployment, I'd say something like Fabric or Ansible is going to be the
simplest way to start.

Hi all!
I announced the Kickstarter project here way back in February and got a

Hi,
I added a screenshot to the readme. I think in general filtering items
from the stacktrace is a good idea, but I am probably doing it too much. I

Hi,
Quickie is a leiningen plugin to autotest clojure.test tests. There don't
seem to be any active projects for clojure.test, so a couple of people at

Is it possible to see *some* of the stack trace so you can debug?
Also you should include a screenshot of what the library looks like in

To Daniel's comment: that's a great idea (I'm sorta new to this whole
releasing-a-library thing so I didn't think of that), and I'll definitely
make a branch for that if I think of a big idea that I want to implement
that involves breaking changes. But I figure that if someone other than me

First, thanks in advance to anyone looking at this,

Tinkering, I find that if I redirect input so that clojure.main reads

with "#_", then I get an error message.

Watch behavior varies a bit by ref type, I believe. You'll probably
want to look into the details of the specific ref type you're using.
for atoms and refs, I believe the watch is done on the thread that's
updating the ref. Since retries can occur you can't really count on
ordering. You could crea

Great stuff!
I'm wondering what's the "realworld" difference between JaCoP and CHOCO.
Why did you choose the former?
